Glee Season 1 Episode 12 : Mattress
When the glee club is left out of the school yearbook, Rachel has the club members cast in a local mattress commercial in an attempt to raise their social status. The team is paid in mattresses, revoking its amateur status and rendering it ineligible to compete at Sectionals. Will discovers that Terri has been lying to him about being pregnant and walks out on her. He spends a night at the school using one of the mattresses, and thus steps down as club director so that the team is eligible to compete, but remains undecided over whether to end his marriage. Emma and Ken schedule their wedding for the same day as Sectionals.
